The median value corresponds to a cumulative percentage of 50% (i.e., 50% of the values are below the median and 50% of the values are above the median).

The median is usually calculated for numeric variables, but may also be calculated for other sequenced variables of a categorical nature, such as the categories in a satisfaction survey: excellent, good, satisfactory and poor.

The median obtained from the cumulative frequency graph (164 cm) is not the same value as the median obtained from the calculation in Example 4 (163.9 cm) or from the stem and leaf plot (163.5 cm).

The median is the middle of a distribution: half the scores are above the median and half are below the median.

In time, the Mesopotamian-influenced religion of the Magi was suppressed in favour of a more purely Iranian form of Zoroastrianism, itself evolved from its somewhat dualist beginnings into the monotheistic faith that it is today (also known as Parsi-ism).

Herotodus also mentions that "the Medes had exactly the same equipment as the Persians; and indeed the dress common to both is not so much Persian as Median." (7.62) "These Medes were called anciently by all people Arians; but when Media, the Colchian, came to them from Athens, they changed their name.

In spite of repeated rebellions by the early chieftains against the Assyrian yoke, the Medes paid tribute to Assyria under Sargon's successors, Sennacherib, Esarhaddon and Ashurbanipal, whenever these kings marched in with their fierce armies.

The rise in poverty and decline in median income primarily reflect the increase in unemployment in 2002.

The drop in median income was concentrated among minorities.

Among a fourth definitional category, the decline in median income was not significant.

Median Filtering(Site not responding. Last check: )

When performing median filtering, each pixel is determined by the median value of all pixels in a selected neighborhood (mask, template, window).

The median value m of a population (set of pixels in a neighborhood) is that value in which half of the population has smaller values than m, and the other half has larger values than m.

Also shown are the median filtering results using 3x3 and 5x5 windows; three (3) iterations of 3x3 median filter applied to the noisy image; and finally for comparison, the result when applying a 5x5 mean filter to the noisy image.

Traditionally, the creator of the Mediankingdom was one Deioces, who, according to Herodotus, reigned from 728 to 675 BCE and founded the Mediancapital Ecbatana (Hâgmatâna or modern Hamadan).

To judge from the Assyrian sources, no Mediankingdom such as Herodotus describes for the reign of Deioces existed in the early 7th century BCE; at best, he is reporting a Median legend of the founding of their kingdom.

Indeed, Astyages and the Medians were soon overthrown by the rise to power in the Iranian world of Cyrus II the Great.

Median(Site not responding. Last check: )

The median for a set of data is the value that is exactly in the center.

Since the median uses only the value or values in the center of the list, the outliers are not used.

The median is used in cases where extreme outliers occur, like real estate prices (there are some really expensive houses) and household income (some people make a lot of money).

Median pay for directors of government and legislative relations there rose 19.4 percent between the current survey and the previous year's, from $49,400 to $59,019.

An increase of more than 13 percent was reported for the median pay of chief public-relations officers at baccalaureate institutions (from $51,000 in 2000-2001 to $58,120 this academic year) and for executives who hold both chief development and public-relations officer titles (from $75,580 to $85,754 this year).

By far the largest decrease in median salary was reported for directors of development and alumni affairs at doctoral institutions: Their pay dropped slightly more than 19 percent, from a 2000-1 figure of $109,125 to this year's $88,265.

But the median amount is $5, since one may divide the group into two groups of 10 persons each, and say that everyone in the first group brought in no more than $5, and each person in the second group brought in no less than $5.

Head fund raisers at master's institutions earned a median of $105,896 during the current academic year, up from $99,599 the previous year, and their counterparts at baccalaureate colleges and universities made a median of $100,970, up from $95,507 in 2001-2.

For the sixth consecutive year, the increase in median salaries for all administrators outpaced inflation, which was 1.5 percent for the 12-month period ending September 2002, according to the U.S. Bureau of Labor Statistics.

Although private institutions saw a larger overall median-salary increase (3.7 percent, compared with 3.0 percent for public institutions), the median salary for all public college and university administrators was 19 percent higher than that of their counterparts at private institutions.

Small lesions or drug injections into the median raphe produce a dramatic behavioral syndrome characterized by astonishingly pronounced hyperactivity, large increases in food and water intake and sexual behavior and a pattern of disturbances in learning and memory situations similar to seen after damage to the hippocampus.

The raphe nuclei are best known as one of the major sources of serotonergic projections to the forebrain, but we have amassed a large body of evidence suggesting that the behavioral effects of raphe manipulations are not due to interference with serotonergic function.

It would thus seem that there is an as of yet unidentified neural system present within the region of the median raphe which exerts an exceptionally powerful influence over a wide variety of behaviors.

Metrowide, the median sale price of single-family houses, condos and townhouses sold through the Regional Multiple Listing Service rose just 0.5 percent for the year, from $228,900 in 2005 to $230,000 in 2006.

That was the smallest increase since the association began tracking median sale prices in 1998 and a startling contrast to the record increases of recent years.

Median sale prices show only what's happening in a broad market; extrapolating to determine the value of homes in a particular community can be futile because markets are highly localized.

Distal median nerve dysfunction is a form of peripheral neuropathy (nerve dysfunction outside the central nervous system) affecting movement of or sensation in the hand, caused by damage to the distal median nerve.

Dysfunction of a single nerve group, such as the distal median nerve, is classed as mononeuropathy.

Wrist fractures may injure the median nerve directly or may present a risk for entrapment of the nerve later on.
